The amount of calories varies by distance walked and also the metabolic rate of the golfer. But fitness experts estimate you'll burn roughly 1,500 calories during a four-hour round. That's 825 calories more--or roughly a Burger King Whopper and some onion rings--than if you ride in a cart.
Interestingly, in most studies, it was only slightly more beneficial to carry your clubs vs. walking with a pushcart. So if you're worried about your back, you don't have to sling your clubs to get a good workout.
